Frost Control - Kubota KX080-3 Workshop Manual

WSM KX080-3 Mechanism
D.Frost control
Function
The evaporator fin temperature is sensed. If detected too low, the compressor is interrupted to prevent
the evaporator from freezing.
a. KX121-3, 161-3
Activating temperature characteristic
Function
The evaporator fin temperature is sensed by a refrigerant-filled capillary tube. If the temperature drops
below a specified level, the pressure in the internal bellows drops too. The contact is now broken to turn
off the compressor clutch power.
